Specication of Letters Patent.

Patented Nov. 10, 1908.

Application led March 22, 1906. Serial No. 307,501.

To all whom 'it may concern.'

Be it known that I, THEoDoRE L. BRUM- BAOK, a citizen of the United States, residing at Stanle ton, in the county of Page an State of ir inia, have invented certaln new and useful Fmprovements in Corn-Huskers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to corn husking machines, and has for an object to provide a machine of the class embodying new and im roved features of economy, convenience an efficiency.

A further object of the invention is to provide machines of the class embodying rotating husking rolls with improved means for ho ding the said rolls yieldingly in operative relation.

A further object of the invention is to provide a machine of the class embodying a shaking screen disposed beneath the husking rolls and of im roved means operative from the' said rolls or actuating the shaking screen.

A further object of the invention is to provide a machine of the class embodyin husking rolls supplied with removable an interchangeable husk-engaging teeth of improved form and construction.

With these and other objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereisafter fully described and claimed.

In the accompanying drawings z-Figure 1 is a top plan v1ew of the improved husking machine, with the ear engaging cover removed. Fig. 2 is a view of the husking machine in side elevation.

Like characters designate corresponding parts throu hout the several views.

In its pre erred embodiment, the improved machine forming the subject-matter of this application, comprises a frame 10 supported in any approved manner, as upon the legs 11, which may be in turn supported upon the base pieces 12. The frame 101s so disposed and secured upon the sup orting means as the legs 11 as to be in an inc ined position as particularly shown in Fig. 2, the inclination being longitudinal of the machine, and sloping toward the conveyer 18 of any approved form. U on the frame 10 arerigidly secured the ilow blocks 14 and p 15 providing alined caring openings for journaling the trunnions 16. and 17 of the rolls 18 and 19, respectively, which are thereby permitted a rotary movement but held from lateral displacement. The trunnion of one of said rolls, as 1,7, is extended as at the shaft 2() outwardly from the machine through an off-set frame (portion 21, and thereupon is ri idly secure any convenient means for a ying power to the said rolls as the belt u e 22.

Adjacent the ends of the illow loc 14 and 15 ,the end pieces of the rame 10 are rovided with apertures 28 and24, exten ing vertically through the said pieces, and therein are secured the levers 25 and 26 by means of plates 27 and 28, rigidly secured to the top surface of the said frame 10, and engaging within a notch or recess 29 and 30, respectively, to form a fulcrum for the said levers. The upper ends of the said levers 25 and 26 are extended above the frame piece 10 las at 31 and 32, and are provided with concaved faces, as 33 and 34, for en aging substantially cylindrical bearing bloc s 35 and 36, in which are journaled the trunnions 37 and 38 of the outer rolls 39 and 40. The lower ends of the levers 25 and 26 extend below the frame piece 10 and are provided with hooked portions 41 and 42, enga ing eye bolts 43 and 44, which extend t rou h other eye bolts 45 and 46, and are provied with com- 49 and 50, whereby the tension of the said s rings is varied. To limit the movement of tlie levers 25 and 26 against the tension of the sprin s 47 and 48, brackets 51 and 51 are provi ed with screws 52 and 53, extend ing therethrough and disposed in the path of movement of the said levers 25 and 26, and adjustable longitudinally to vary the movement of the said levers. The several rolls 18, 19, 39 and 40 are provided with internally screw-threaded openin s for receiving teeth 54, externally screw-t readed to enga e the several openings and divided longitu inally from each end upon a plane 55, diametrical to the said teeth, forming shoulders 56, which, when in operative position register substantially with the external surface of the rolls and with the remaining upstanding half of the tooth beveled as at 57 to form a spur outstanding from the face of the roll positioned to engage loosely within openings 58 formed in the opposing roll. Instead Of leaving the u standing portion of the tooth to present a dIfametrical plane, the said portion 1s cut away as at 56 to form an upstanding portion substantially triangular in cross section and with the apexV of the triangle moving forwardly to pass between the kernels u on the ear whereby shellin of the corn -is llsirgely obviated. While t e said rolls may each be provided with teethas described throughout their entire length, it is Vfound in practice that it is unnecessary to supply teeth to all of the said rolls at their lower or rear ends, for the reason that the ears of corn, when first introduced into the machine, are inclosed in husks of greater thickness, which require a great number of teeth to remove, and that as the work of huskin progresses, the greater the number of teeti the greater amount of' corn will be accidentally shelled from the ear, and it has been found, in practice, advisable to omit the teeth from the lower or rear ends of one of yeach pair of co-actin rolls, as shown in the center rolls particulay in Fig. 1.

For communicating motion from lthe roller 19, which is positively driven from the shaft 2-0, the several rolls are provided with intereng-a'ging gears as 59, 60, 61 and 62, whereby the said Trolls are rotated in therdire'ctions as indi-cated by the arrows in Fig. 6, and a ear 'Wheel 63 is secured to one end of the mac ine enga' ing one yof the said (gears as 60, yand provi e with any approve means as'the crank 64 for rotating the said gears and rolls manually, "when it is found desirable for any purpose to 'so operate them.

Beneath the roll'sis--disposed a screen 65 of any approved construction'and"supported by means of links 66, pivotally secured tothe "legs-1 1 at one end, `and to oneside of the screen 65 at their other ends, while tlreother side of the screen is supported by mea-ns of a lever 6 7, rigidlyse'cured upon a shaft v68, mounted in bearings 69, rigidly secured to the legs 11, and disposed at an inclination substantially in parallelism with the rolls. At the forward end of the machine, the shaft 68 is bent to form a crank arm 70, connected by means of the pitman rod 71 with the wrist pin 72 carried upon one of the gears, as 60, from which the shaft 68 receives an oscillating motion. Longitudinally of the machine and between the end legs 11 is secured a resilient rod 73, about the middle of which is secured a clip 74 with a strip 75 extending therefrom and rigidly secured to the' screen 65, as shown 1n detail in Fig. 7, and preferably by means of bolts 76 which also secure upon the upper side the cli 77 to which is pivoted the crank arm 67. T e resilient rod 73 serves to support the screen and to impart thereto a peculiar springy or jerky motion by which ernels of corn are dislod ed from the meshes of the screen and toget er with the husks thrown off. Beneath the screen 65 is secured the usual apron 78 inclined from opposite sides toward the middle and toward one end for delivering material therefrom to a conveniently disposed receptacle.

Above the rolls, as a protection, is disposed a cover 79 comprising side pieces extending longitudinally of the machine and positioned upon the outside of and adjacent to the outer rolls 39 and 40, and with cross pieces, as 80, adjacent the upper end of the machine and with a long piece or covering member 81 at the lower end of the machine defining an opening 82 adjacent the upper ends of the rolls and through which the material is fed to the machine. Extending longitudinally of the machine and between the middle rolls 18 and 19 is adivision strip 82 and between the said -division strip and the side pieces are hin ed down-hanging plates 83., Which,in norma position, extend towards the upper surface of the rolls and serve to hold the vears of c f in operative positions between the said ro ls, while the husks are being removed therefrom. rIhe vdown-hanging plates 83 preferably diminish in weight from the upper toward the lower end of the machine, for the reason that when the ear of corn is, provided with a greater number of husks,vgreater weight is :desirable to hold the ear 'in contact with the husking roll. To accomplish the difference in weight of the said plates, they are preferabl constructed e ual `in dimension lon itudinallry and laterally, ut increasing in thic ness from the lower toward the upper end yof the machine, as shown in Fig. 8. The plates 83 may be hinged in any :preferred manner', but it .is found advisable to `secure them by means of staples 84 in 'the cover member 81, and staples 85 in .the upper om theinner an cover member 81. The said cover member 81 to which the plates 83 are hinged is arranged for vertical movement between the side ieces 79 by means of slots 81 through whic are extended screws or other clamping .5 means 81 so that the said lates may be raised or lowered relative to the rolls for the j; accommodation of ears of varying sizes and husks of varying thicknesses.

While it is designed to supply the machine onl with ears of corn removed from the sta ks, it sometimes happens that stalks are accidentally inserted into the machine and to 11gravide for disposing of such stalks, the ro are provided with ongitudinal grooves l 86 having each a shouldered side 87 which are in Hosition to engage a stalk lyinglongitudina y between the rolls and to provide 1ny creased space to permit the passage of the stalks between the rolls. In case the stalk is not removed from the ear while assing through the rolls, it may interfere with the passage of the ear from the lower ends of the rolls to the conveyer and to provide for such passage the lower end of the side pieces of the cover 79 is provided with an aperture or o 88 of any approved form, herein s own 1n semi-circular and with a door or covermember 89 hinged thereover as at 90 and eld normally in a closed position by means of a spring 91 secured one end to the door and the opposite end to the side piece. In o eration 1t will be understood that jerk corn will be fed to the machine by dropping ears continuously through the feed opem 82 upon the upper surface of the upy per en of the husking rolls 18, 19, 39 and 40, which are rotated by means of the rotating shaft 21 and the interengaging gears 59, 60

61 and 62. The inclinatlon of the rolls will cause the corn to move toward the rear end of the machine in the usual well known manner, and in its passage. husks will be engaged by the teeth 54 to aw them between the ift-.hns rolls, which will finish the removal of the usks from the ear whereu on the ear drops downwardly through the o -set frame 21 mto the conveyer 13 which may be of any approved form and construction. In the process of husking) some corn will be shelled from the ears ei operated upon and will fall between the ro s with the husks which have been removed from the ears and drop upon the screen 65. The movement of the screen provided by the oscillating shaft 68 and crank arm 67 causes the husks to be thrown from oil' the screen, while the shelled ..1 corn passes through the screen upon the A apron 78 and downwardly into any convenient receptacle in the usual well known manner.

The construction of the husker above described is such that blast fans for cleaning shelled corn may be and are preferably omitted from the structure whereby cracked or artially powdered kernels of corn caused by being engaged with the husking teeth is not blown away and lost.
